Describe your taste in music with a few select words.

http://www.allmusic.com/cg/amg.dll?p=amg&sql=75:

Atmospheric, bleak, brooding, cerebral, cold, distraught, dreamy (at times), ethereal, fractured, gloomy, intense (at the best of times), malevolant, melancholy, nocturnal, paranoid (a select few), sentimental, spacey, sparse, sprawling, suffocating, visceral (when in the mood)

recall the past and dream of future

Calm/Peaceful, Delicate, Dreamy, Fun, Gentle, Happy, Intimate, Laid-Back/Mellow, Nocturnal, Nostalgic, Passionate, Reflective, Relaxed, Restrained, Sentimental, Sweet, Warm, Yearning

'Tis a good list, no?

Interesting. That's about it. Heh heh. As long as it's interesting, I like it.

Nostalgic, reflective and melancholy. Sometimes ethereal.

Bitter, bittersweet, calm, carefree, complex, delicate, dramatic, dreamy, elegant, gentle, harsh, hypnotic, innocent, light, melancholy, nocturnal, playful, reflective, relaxed, soft, somber, soothing, sophisticated, sweet, warm, wintry. Also longing, but too bad they don't have it...

While we're at it, could we arrange a list of recommended songs to fit these genres?

Well I'd like to recommend an album.

Yoshimi Battles the Pink Robots by the Flaming Lips borders on the dreamy, dreary and ethereal. Good music to sleep to.

Soft, Smooth, Calm/Peaceful, Gentle, Sad, Bittersweet, Carefree

I would recomend the soundtrack to Chrono Cross, has some nice sleepy music too :D

NOTE: Flaming Lips, music and sleep doesnt sound like a good combo O_o

...Uhh, does that mean you have listened to the Flaming Lips?

Sparse and sprawling are Sonic Youth. I'm currently getting through Daydream Nation, highly recommended album.

Soft, Smooth, Ethereal, Nostalgic, Aching Desires awakening, happy, energetic, viewing a future self....(don't know if that counts :) )

Do you guys ever get your moods completely changed as you play a song and you REALLY get into it...
I hate it since sometimes i end my piano rampage with a sad song and ... some of those features mentioned above show up...

Nostalgic, Melancholy = "Lavinia" (The Veils)
Cold, sad = "Mad World" (Gary Jules)
